Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed July 19, 1906. Serial No. 326,898.

' tion, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to sleds, and more particularly to. attachmentstherefor, and has for its object to provide a wheel attachment soconstructed that the wheels may be easily and quickly moved into and outof position to support the sled with the runners clear of the ground, sothat it may be easily transported over areas free from snow.

Another object is to provide an attachment adjustable to suit sleds ofdifferent sizes.

It is to be understood that I do not desire to be limited to the exactdetails of construction shown and described, for obvious modificationswill occur to a person skilled in the art.

In the drawings forming a portion of this specification, and in whichlike characters of reference indicate similar parts in the severalviews, Figure 1 is an elevational view of a sled provided with thepresent invention. Fig. 2 is a top plan view of the attachment removed.Fig. 3 is a horizontal section showing the lower frame in top plan. Fig.4 is a central longitudinal section on line 4 4 of Fi 2.

fteferring now to the drawings, there is shown a sled 5, includingrunners 6, connect ing-bows 7, and the usual top board 8. A frame 9 issecured to the bows by means of clamps 10, and, as shown, this frame 9consists of longitudinally-extensible side members 11 and extensibleconnecting cross members 12, bolts 13 being provided to hold theseextensible portions at different points of their adjustment.

The side members 11 each have a pair of forward and rearwardinwardly-offset portions 14 and 15, respectively, and rearwardly of eachof these offset portions there is seciu'ed to the respective members 11a forwardly and upwardly inclined guide 16, these guides extending intothe offset portions.

A longitudinally and laterally extensible intermediate frame 17 islocated beneath the frame 9 and Within the inclosure of the guides 16,and this frame has journaled thereupon a plurality ofoutwardly-extending rollers 18, one of which is engaged in each of theguides 16. These rollers are mounted upon shafts 19, which extendoutwardly therebeyond and which are engaged in the upper ends ofvertical longitudinally-extensible supp ortinguprights 20, theseuprights being secured at their lower ends to a frame 21. This frame, aswell as the frames 9 and 17, extends horizontally, and it consists ofextensible side members 22, having axle-receiving notches 23 in theirunder surfaces, and secured in these notches there aretransversely-extending longitudinally-extensible axles 24, having wheelsrevolubly mounted upon their outer ends. The side members 22 areconnected by forward and rearward extensible cross members 24 and 25,respectively, and by an intervening cross member 26. These connectingmembers and the connecting members 12 of the upper frame 9 consist eachof two overlapped sections A and B, which are provided with registeringlongitudinal slots C, receiving the clamping-bolt 13 above referred to.

A longitudinally-extending supportingplate 27 is disposed beneath therearmost pair of connecting members 12 and has bolts 28 engaged thereinand in the slots C of these members. It will thus be seen that althoughthese members are extended the plate 27 being movable with respectthereto may be positioned midway between the side members 11. A lowersupporting-plate 29, corresponding to the plate 27, is secured upon theconnecting members 25 and 26 in a similar manner by means of bolts 30and may thus also be positioned centrally of the members to which it isattached. The rearward ends of these plates 27 and 29 are bifurcated, asshown at 27 and 29, respectively, and pivoted in the bifurcation 27there is a vertically-extending hand-lever 31. The lower portion of thishand-lever is longitudinally slotted, as shown at 31, and the slotreceives a horizontal roller 32, which is journaled within thebifurcation 29 of the plate 29. As shown, the hand-lever 31 isadjustable vertically with respect to the plate 27, having a pluralityof openings 33, in which its pivot-bolt 34 may be engaged. Ahanddogand-rack mechanism 35 is provided to hold the lever at differentpoints of its pivotal IIO in which the rollers 18 are engaged, and thewheels will thus be brought above the runners 6. Reverse movement of thelever will of course bring the wheels into operative position and theattachment being longitudinally, transversely, and vertically adjustable5 is adapted for attachment to suit sleds of different sizes.

The dog-and-rack mechanism 35, referred to above, includes a hand-leverX and dog Y, which are connected by an extensible link Z,

this link permitting of the vertical adjustment of the lever 31, as willbe readily understood.

What is claimed is 1. An attachment of the class described 1 comprisingan extensible frame, attaching devices carried by the frame, guides adustably connected with the frame, a second frame connected with theguides for movement diagonally toward and away from the first frame,wheels connected with the second frame, said frame beingadjustable, alever connected with the first frame for pivotal movement, andconnections between the lever and the second frame for movement of said.frame toward and away from the first frame when the lever is moved.

2. An attachment for sleds comprising an adjustable attaching-frame,guides carried by the frame, rollers engaged in the guides, anadjustable frame located below the at taching-frame, adjustableconnections between the rollers and the lower frame, means for movingthe lower frame longitudinally,

said guides being arranged to move the lower frame upwardly when it ismoved longitudinally, wheels connected with the lower frame, and meansfor holding the lower frame at different points of its movement.

In testimony whereof I afiiX my signature in presence of two witnesses.
